can-DUMP.

Be it'known that I, -G 'EORGE O. BRADLEY,

. citizen of the United States, "residing at Salt Lake City, in thecounty'of Salt Lake and State of Utah, have invented certain new anduseful Improvements in Car- Dumps, of which the following is a full,

clear, and exact description, reference being I had to the accompanyingdrawings, forming a art hereof.

y invention has relation to improvements in car-dumps; and it consists*1n the novel construction and arrangement of parts more fully set forthin the specification and pointed out in the claims.

In the-drawings, Figure 1 is a side elevation of the main dumping frameor tipple with cars in position thereon ready for dumping, also showinga portion of the main track leading to the dumping frame; Fig. '2 is-acombined end elevation and vertical cross-section on the line 22 of Fig.1, the operating cy'hnder being in section; Fig.

3 is a combined end elevation and vertical cross-section onthe line 3-3of Fig. 1, with V cars rocked to dumping position; Fig. 4 is acombined jend elevation and vertlcal cross section (with parts broken) on the line4-4 of Fig. 5 showing the apron attachment by which the ore or othercontents of the car may be discharged to a convenient distance from theside of the car;.a-nd Fig. 5 is a side elevation of Fig. 4 with part ofthe apron brokenaway. i 1

of tro The object of my invention is. to provide suitable -mechanism'for the dumping -of cars (and notably cars handling ore, rock,

coal and. the like which will dispense with the necessity ofany overheadconstruction thereblyi permitting where desirable, the'use withoutinterference.

- Afurther object is to permit the dumping ofpne or; more cars withoutthe necessity of uncoupling ;;the same from adjacent cars.

A furtherobjectis' to utilize compressed air, steam,.;waterorany-equivalent fluid as the driving means. for, actuating the dumpingmechanism-the latter being coupled to the piston 0f a single cylindervutilizing such driving fluid; thereby not only simplifying the generalconstruction of-the a paratus, but-insuring therefor, a perfect anreliable automatic action under perfect, control of the o eratol'is Aurther object: is to providemeans for;

the rails of the track or tramway overwhich the-cars 2 arehauled, saidrails leadin up to the rails P of the oscillating orv roc ng dumpingframe or. tipple. Said dum mg.

frame may be constructed in any mec any ical manner with a View ofsecuring strength .and rigidity,- but preferably as shown inthedrawings, that isto say, it is composed of;

curved members or rockers E connected lon-.

-gitudinally by I-beams F, to which the rails P are secured, the ends ofthe I-beams being.

secured or riveted to the transverse plates or sheets 3 to which theangle-beams com osing the rockers E are fastened. The e ges. .of theplates 3 are surmountedby struc-- tural members. or. angle bars 0? asshown,"

is connected through theconnecting rod K,

to the end of one arm of a bell-crank lever K ivoted at the bottom ofand between the;

. ang e-bra'ckets L one leg of each of whichis riveted to the web of oneof the I-beams E, the other leg being riveted to the bottom flange of.the opposite beam F, asshown. Loosely ivoted between thevertical-members of tiie bracketsLis a lockmg-pawl K in the shape. ofanangle-piece, the locking.

end being the heavier and when released Iceing free. to en age the endof the adjacent arm ofthe bel -crank K when the latter .1s The lockingarm of the pawl isowe'ver, normallylheld inwa hor zontal position by.thestop 1L .wheutho dumpin frame, is in normal position.-and

before. the..-sa.me is tilted (Fig. 2. but the;

shaft or tumbling shaft M to which is se- I to the tumbling-shaft in sM, M, is an arm -L'- to whlch 1s pivot-.

spring Q which normally tends to cured the tipple-arm N (extending intwo directions from the shaft) The opposite ends of said tipple-arm areP1V0tall coupled to the inner ends of. the links w ose' outerends arepivoted to the adjacent ends of the arms N? keyed to the dog-shafts Owhich are mounted in bearings '0 cm thedumpingframe. The links Npassthrough the I-bea'ms F with am Is clearance. Keyed between the bear--al y connected one end of a link L the op posite end thereof beingpivotally connected to the'adjacent arm' of the bell-crank K Each dog isadapted to engage a stirrup 0 depending from the center 0 the side ofthe car'as shown.

Mounted at. the bottom of the car behind one of the stirrups O and inthe path of travel of-the nose R of one of the dogs 0, is areciprocating latching plunger-rod Q mounted in a bearing 7, the outerend of the plunger terminating in a head P which the nose R of the dogengages. On the rod Q are collars 8 which serve to confine the end. ofan arm P mounted at the center of the shaft MP ,To the oppositeprojecting ends.

of the shaft P are secured arms Q which are pivotally connected throughthe medium of links P to the latches P the free ends of which for aclosed position of the hinged door Bengage the angle-bar 9 carried by!Said door. Interposed between the bearing 7 and adjacent collar 8 andencircling the latching plunger rod Q is. an ex andingt drce the rod Qoutwardly and thus, through the connections P?,Q and P to elevate thefree ends of the latches P into engagement wlth the gate 'or door D.

Leading from opposite ends of the operatin cyhnder K are dpipes K?alternately servmg as supply an exhaust plpes, the upper ends thereofterminating 1n the valvecasmg Kin which the control-valve is actuatedbythe lever. 10, the supply of the motor fl'uid (steam, compresse air,water, or equivalent fluid) being furnishedby a pipe 11 leadin from anysuitable source y turnin the control valve to one position motor fluiwill be admitted to one side of the piston4, and by turning to anotherposition, said fluid: willenteron the opposite side of the piston,driving it first mechanism being herein shown only conventionally', asany means for reciprocating the piston mlght be utilized in the presentconnection.

Referring now to the parts thus far described, the operation of -thedumping appara-tus may be described as follows Assuming the dumpingframe to be in its normal horizontal position, with the rails P thereofin continuation of the track-rails 1 (Figs. 1 2) and with two carsresting on the dumping frame as shown; assuming too' that the piston 4of the operatin cylinder K is at the end Of its inner stro re; thereuponthe operator turns the control valve, sufiiciently t0. admit the motorfluid behind the piston to drive it forward or outward. With the travelof the piston represented b the distance a -b (Fig. 2 the bell-crankwill be rocked to bring t e end of its inner arm in position tobeengaged b the lockingarm of the pawl K, a positive locking takingplace the moment the tipple or rocking frame hasbeen oscillatedsufficiently to disengage the vertical arm of the pawl from the stop L".A further draft on the connecting rod K by the continued travel of thepiston in the same direction'will effect the disengagement as isobvious. In the travel of the piston through the distance aA-b, byreason of the intermediate connections L, L between the bell-brank K andtumbling shaft M, the latterwill be rocked, thus oscillatingthetipple-arm N in adi rection (contrary to the hands of a clock,

Fig. 2) to push on the links N" and thus, through the arm connections Nrock th of the dogs" is forced against the terminal head P of thereciprocating rod Q,'thereby forcing the latter inwardly against theresiliency of the springQ, the inward movement of the rod oscillatin thearm P. which in turn rocks the shaft P in roper direction to depress thearms Q an links P thereby withdrawing the latches P from enga ement withthe hinged door D. The latter is-thus free to swing 0 en as-the cartilts. With the travel of tie piston through the space represented by bc2) the dump is thrown into the position shown in Fig. 3, the gate ordoor D swingmg open and the contents of thecar or cars dischar 'ng. Whenthe ore has all been dumpe fromthe car, the operator reverses thecontrolling lever forcing the piston moss frame is brought back tonormal position,

the vertical leg of the locking pawl K l-strik- 1 ing the stop L andreleasing the crank-lever K"; and when the piston has passed through itsfinal travel b-a, the dogs are "again disengaged from their sti'rrupsand oscillated to their original position shown in Fig.

' 2, the spring Q. forcing-"the rod Q outwardly which causes the latchesP to retingage the edge of the gravitating gate or door D.

' The tipple or dumping frame while herein accommodating two cars, maybe built for one, two or more cars, asobviousf 'Itwill be seen that thecurve of the rocker E of the dump has a true radius from the center ofthe 'draw-hcads or couplings between the cars, so that both car anddumping frame rotate about the axis of the draw-heads. This arrangementpermits the dumping of a car on the tipple without the necessity ofuncoupling'the same from thecar on the main track,the ordinary-link andpin coup ler between the cars allowing for the neces sary tilting of acar to discharge its con-- tents. Any kind of coupler however, may beimprovised. whose draw-head will allow for the rotation necessarilyimparted to a car to dump the same.

"Where it becomes desirable to discharge the material some distance awayfrom the car, as where for example the ore is charged into a furnace.the attachment shown in Figs. a and 5 is resorted to, and may be .InFigs. 4 and 5 parts already fully illus-f trated in Figs. 1, 2 and 3havebeen omitted for the sake of clearness, so as to bring out no describedas follows :-'lhe dog-shaft O has secured thereon at points opposite theends of the car, arms S from which extend the links S, the latter beingin turn pivotally connected to the opposite ends of an apron S Disposedalong the bottom of the apron to one side (toward the car) of thelongitudinal center thereof are lugs or ears 12 which loosely engage arod 13 mounted between the upper extensions of the rockers E,

E. Theends of the apron are turned up to confine the material on themain body of the apron. .,,;When the dogs are'forced into en-- gagemeirt with the car s'itirrups O preparatory to dumping, the-"rocking of thedogshaft to effect said engagement forces the parts S, S upwardly, thuscausing the apron to assume the dotted position shown in Fig.- beforethe car is tiltedf When tilted, the gate D swings open and the ore runsover the apron as obvious from the drawings. The apron attachment isomitted from Figs. 1, 2, 3 as it would obscure the other parts. Besides,not being necessary in all cases, but

only in special connections such as charging furnaces and the like, itsillustration in separate views simplifies the description.

the apron feature more conspicuously.

Such featuresjof construction as may be shown in. the drawings, but towh ch no reference is herein made, are well known in the art and requireno detailed description.
